` 1 claim. `(o1. 298-23) The subject of the invention is a new and improved truck or carriage for refuse disposal.

The rst and main object of the invention is to provide a truck or carriage for refuse disposal, by the use of which the said work can be done more easily and more economically, in so far as the work can be done by one man or two men instead of the usually needed three men, and the work itself is less hard as compared with the work in servicing the hitherto used garbage collecting trucks or carriages. Another object of the invention is to provide a refuse collecting truck or carriage, in which the refuse put into it through lateral window openings can be distributed or shifted in it by a rotation of the receptacle round its longitudinal axis, in such manner, that the window openings and the inner space near them are always unobstructed for new loads to be taken in. Still another object of the invention is to provide a refuse collecting truck or carriage, the contents of which can be disposed of by tilting its container round its rear end,

` which latter is provided with a trapdoor.

These and other objects of the invention, and the technical means for realizing them will be made perfectly clear by the following description of a preferred embodiment of a new and improved reiuse disposal truck, with reference to the drawings showing it, in which drawings the Figures 1, 2, and 3 are a top plan view, a front side elevation and a rear side elevation respectively of the new and improved truck set into position ready for refuse-collecting work; Figures 4 and 5 are a side elevation and a front end View respectively of the truck set to or raised into the position for refuse disposal or dumping work; Figures 6 and 7 are, in reduced scale, a partially sectioned View of the front end and of the rear end respectively of the truck set into refuse collecting position as in Figs. l to 3; Figures 8 and 9 are, in reduced scale, a partially sectioned view of the front end and of the rear end respectively of the truck set into position for transportation, in which position the refuse containing receptacle is shifted round its longitudinal aXis for about degrees as compared with Figs. 6 and 7.

Referring now to the details of the drawings the illustrated embodiment shows the chassis II of the truck running on the wheels I2, but the drvers cabin and the hood with the motor and the power transmission for driving are not shown, as Athey may be of any standard type for motor trucks. The chassis of the truck carries a refuse collecting drum I3, the two ends of which are rested on approximately semicircular socles I4, I 5,

so that the drum may be revolved round its longitudinal axis. The front socle I4 is xed on the chassis, whereas the rear socle I5 is hinged to the chassis, so that it may swing round its hinges, as seen in Figure 4. The closed front end of the drum I3 has xed to it the hub of a worm wheel IS, which latter meshes with a worm I'I on a shaft I8, journalled on the chassis and provided with a sprocket wheel I9, spanned by the chain 2U, which goes to a motor or part of the power transmission controlling the revolving movement of the refuse drum I3. The hub of the worm wheel I6 ends into a trunnion 2 I, which rests in the jack 22, and the bearing bowl 23 as well as the turnable bushing 24 contained therein have an upper slot, so as to allow the trunnion 2| to be lifted out of the bearing, if the drum I3 is to be tilted for discharging it.

The refuse receiving drum I3 has on its one longitudinal side a number of (three) window openings, 24, the lids of which, 25, marked in the drawings by fringe-dotting, can slide within guiding ledges 2G, extending over a corresponding part of the circumference of the drum I3. The Figure 2 shows the rst window 24 opened, whilst the other twol windows are closed by their lids. The Figure 4 shows, that the rear end of the refuse containing drum is closed for about one third of its height by a Xed shieldplate 21, and for the lower two thirds of its height by a trapdoor 28, which is hinged to the shieldplate 21 along the line 29. The free swinging end of the trapdoor 28 can be Xed to the spoutlike end 3D of the drum I3 by means of the latch 3 I, to be passed through the eyelet 32. At the side of the drum opposite to the window openings 24 is a longitudinal slidable bar 33 with a handle 34 at its front end, and the jointed rear end 35 of this bar engages a bar 36, which is crossingly xed to the trap door 28, so that, with the latch 3| being unhooked, the trapdoor 28 can be swung open by shifting the bar 33 with the handle 34 towards the rear end of the drum I3 (see Fig. 4). This will be done, when the drum is to be emptied by tilting it round its rear end. The mechanical tilting device comprises a guideway |35, extending on the circumference of the drum for about half its length, along which guideway rolls the caster at the swinging end of the drum-lifting arm |36. Two pulleys or chaindrums 31, which are xed on the shaft of the tilting arm 36, are controlled by means of chains 38, coming from a corresponding counterpulley or drum 39, which belongs to the gearing 4D, and this gearing 4|), by means of the chain 4|, is operated by a special drum-tilting motor or transmission derived from the general power plant of the truck. The longitudinal beam of the chassis, at the side on which the refuse receiving Windows are provided on the drum, carries, hinged to the beam, a narrow platform or step 42, on which the refuse collecting workmen may step or deposit the ash-cans or the like, to facilitate the emptying of such ashcans into the drum through the opened windows 24.

It is to be understood that the invention is not restricted to the illustrated and above described embodiment, but its structural features may be changed in adaptation to special conditions of different applications, without departing from the scope of protection of the following claim.

What is claimed is:

In a refuse disposal truck'or carriage, having a chassis and a refuse containing revolvable and tiltable drum with lateral refuse receiving window openings and a rearwardly arranged refuse discharging opening; a spoutlike prolongation at the rear end of the drum; a shield-plate covering a part of the rear end of the drum; a trap-door hinged at the said shield-plate and covering the rest of the rear-end opening of the drum; a latch at the swinging end of the trap-door; an eyelet to catch the latch at the end of the said spout; a bar xed transversally on the swingable trapdoor; and a bar, xed longitudinally slidable on the one longer side of the drum, said bar having a handle at its front end, and having' at its rear end a jointed prolongation which engages the first said transversal bar on the trap-door.
